The LL-100 laser level measurement sensor is used for level control, plugged chute detection, and monitoring buildup. This non-contact device can be used in bulk solids, pellets, or granular materials of all material dielectrics in a variety of vessels. It measures in a tight 1° beam, so there is no beam divergence, making it suitable for use in very narrow vessels or constrained spaces. Narrow beam laser measurement technology is resistant to reliability issues caused by surface angle, slope, texture, granularity, or material color.
